Description

Technical Field

[0001] This utility model relates to the technical field of valve opening mechanisms, specifically the valve opening mechanism of a heavy-duty mechanical drainer. Background Technology

[0002] A valve opening mechanism is a device used to open valves, allowing fluid to flow normally in systems such as pipelines. Valve opening mechanisms are generally classified into manual, electric, and pneumatic types. Electric valve opening mechanisms use a motor to provide power; the motor's rotational motion is reduced in speed by a reducer and converted into the appropriate torque and speed for opening the valve. Electric valve openers typically have remote control capabilities, allowing operation from a control room or other secure location.

[0003] Heavy-duty machinery generates a large amount of condensate and other liquids during operation, which need to be drained promptly. The valve opening mechanism can accurately open the drain valve according to set conditions and requirements, allowing accumulated water to drain smoothly. This ensures that excessive water accumulation inside the equipment will not affect normal operation and prevents water from causing corrosion, wear, or other damage to mechanical components. The valve opening mechanism has the capacity to withstand and handle large volumes of high-pressure drainage, and can reliably open the valve under high loads, ensuring that the drainage system can cope with the large drainage demands generated by heavy-duty equipment without malfunctioning due to excessive pressure or water volume.

[0004] According to the authorization announcement number CN 209939509 U, an automatic valve opening mechanism is disclosed, comprising a rotary motor, a torque limiter, a rotary flange, a linear bearing, a spring, an extension shaft, and a rotary nylon sleeve. The torque limiter is fixed to the output shaft of the rotary motor by screws. The left end face of the torque limiter is fixed to the rotary flange by a bolt assembly. Several linear bearings are fixed to the left end face of the rotary flange by screws. An extension shaft passes through the linear bearings. The right end of the extension shaft is exposed on the right side of the rotary flange and is limited by a limiting end plate on the extension shaft. A rotary nylon sleeve is sleeved on the left end of the extension shaft. A spring is sleeved on the extension shaft between the rotary nylon sleeve and the linear bearing.

[0005] Existing valve opening mechanisms may not be able to adapt to high-pressure drainage during use, resulting in a decrease in the stability of the valve opening mechanism and affecting the normal valve opening of the drainer. Therefore, a heavy-duty mechanical drainer valve opening mechanism is now needed. Utility Model Content

[0006] The purpose of this utility model is to provide a valve opening mechanism for a heavy-duty mechanical drainer, which assists children in side-lying by using a swingable limiting platform and a phototherapy lamp on the outside of the sleeping seat, and provides a prone position for children by using a detachable arc-shaped cover, thereby solving the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The valve opening mechanism of the heavy-duty mechanical drainer includes a drainer body, a drain pipe is installed through the side of the drainer body, and a valve is installed in the middle of the drain pipe.

Several sets of fixing rods are mounted on the side of the first fixing plate corresponding to the valve. The sets of fixing rods are inserted and installed in the middle of the valve. A second fixing plate is snapped onto the outer arc surface of the first fixing plate. Several sets of clamping blocks are movably mounted in the middle of the second fixing plate. The inner walls of the sets of clamping blocks are all attached to the outer arc surface of the valve.

[0010] Preferably, a fixed base is installed at the bottom of the drive motor, an L-shaped plate is installed on the side of the fixed base, and the outer arc surface of the second fixed plate is installed on the top of the L-shaped plate.

[0011] Preferably, a rotating disk is installed on the side of the first fixed disk at the middle of the rotating shaft, and a number of limiting grooves are symmetrically opened in the middle of the rotating disk.

[0012] Preferably, a limiting rod is movably installed inside each set of limiting grooves, and each set of clamping blocks is installed on the side of the corresponding limiting rod.

[0013] Preferably, the rotating disk has an annular groove inside, and several sets of locking blocks are symmetrically installed on the outer arc surface of the rotating shaft inside the annular groove.

[0014] Preferably, the inner wall of the annular groove is provided with a plurality of sets of circular grooves, each set of circular grooves is equipped with a spring, and one end of each set of springs is equipped with a snap-fit ​​block inside the annular groove.

[0015] Preferably, the second fixing plate has several sets of sliding grooves in the middle, and each set of clamping blocks is slidably installed inside the corresponding sliding groove.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When the drain needs to drain water, the drive motor is started, which drives the rotating shaft to rotate, thereby causing the first fixed plate and the fixed rod on its side to rotate, which in turn causes the valve to rotate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides: a valve opening mechanism for a heavy-duty mechanical drainer, such as... Figures 1-5 As shown, it includes a drain body 1, a drain pipe 2 is installed through the side of the drain body 1, and a valve 3 is installed in the middle of the drain pipe 2. The drain pipe 2 is used to drain water from the drain body 1, and the valve 3 is used to control the opening and closing of the drain pipe 2.

[0026] A drive motor 4 is mounted on the side of valve 3. A rotating shaft 5 is keyed to the output end of the drive motor 4. A first fixing plate 6 is fixedly mounted on one end of the rotating shaft 5. Several sets of fixing rods 7 are mounted on the side of the first fixing plate 6 corresponding to valve 3. The sets of fixing rods 7 are inserted and installed in the middle of valve 3. A second fixing plate 8 is snapped onto the outer arc surface of the first fixing plate 6. Several sets of clamping blocks 9 are movably mounted in the middle of the second fixing plate 8. The inner walls of the sets of clamping blocks 9 are all attached to the outer arc surface of valve 3. When the drive motor 4 is started, the rotating shaft 5 is driven to rotate. The first fixing plate 6 and the fixing rods 7 on its side rotate accordingly, rotating valve 3 and opening valve 3 to drain water from the drain body 1. When the rotating shaft 5 rotates, it drives the second fixing plate 8 to rotate, causing the clamping blocks 9 to slide inside the groove and clamp valve 3. The auxiliary fixing rods 7 drive valve 3 to rotate, increasing the stability of valve 3 when opening.

[0027] Preferably, a mounting base is installed at the bottom of the drive motor 4, and an L-shaped plate 10 is installed on the side of the mounting base. The outer arc surface of the second fixing plate 8 is installed on the top of the L-shaped plate 10. The L-shaped plate 10 installed on the side of the mounting base at the bottom of the drive motor 4 is used to fix the second fixing plate 8, so that the second fixing plate 8 will not rotate with the rotation of the shaft 5.

[0028] Furthermore, a rotating disk 11 is installed on the side of the first fixed disk 6 at the center of the rotating shaft 5. Several sets of limiting grooves 12 are symmetrically opened in the center of the rotating disk 11. The rotating disk 11 installed in the center of the rotating shaft 5 is used to fix the limiting rod 13. The limiting grooves 12 opened in the center are used for the limiting rod 13 to slide, thereby driving the clamping block 9 to clamp the valve 3.

[0029] Furthermore, each set of limiting grooves 12 has a limiting rod 13 installed inside, and each set of clamping blocks 9 is installed on the side of the corresponding limiting rod 13. The limiting grooves 12 are used to limit the limiting rod 13. When the rotating shaft 5 drives the rotating disk 11 to rotate, the limiting rod 13 will move inside the limiting groove 12, causing the clamping block 9 to slide inside the slide groove 18 to clamp the valve 3 and assist the fixing rod 7 in working.

[0030] It is worth noting that the rotating disk 11 has an annular groove 14 inside. Several sets of locking blocks 15 are symmetrically installed inside the annular groove 14 on the outer arc surface of the rotating shaft 5. The annular groove 14 is used to lock the locking blocks 15 outside the rotating shaft 5. When the rotating shaft 5 rotates, the locking blocks 15 are locked on the side of the locking block 17, and the rotating disk 11 will rotate accordingly. When the clamping block 9 clamps the valve 3, as the rotating shaft 5 continues to rotate, the locking blocks 15 will contact the locking block 17 and push the locking block 17. At this time, the locking block 17 and the spring 16 will retract into the circular groove, so that the locking blocks 15 can rotate in the annular groove 14, thereby realizing a more stable valve opening operation for the valve 3.

[0031] Specifically, the inner wall of the annular groove 14 is provided with several sets of circular grooves. A spring 16 is installed inside each set of circular grooves. One end of each set of spring 16 is located inside the annular groove 14 and a locking block 17 is installed. The side of the locking block 17 is arc-shaped. When the clamping block 9 clamps the valve 3, the locking block 15 will push the locking block 17, and the locking block 17 and the spring 16 will retract into the circular groove, making it convenient for the locking block 15 to rotate.

[0032] More specifically, the second fixed plate 8 has several sets of sliding grooves 18 in the middle. Each set of clamping blocks 9 is slidably installed inside the corresponding sliding groove 18. The sliding groove 18 is used to limit the clamping block 9, so as to ensure that the clamping block 9 can better clamp the valve 3 and ensure the stability of valve opening.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
